Polarization implies the isolation of the negative and positive charges present inside a material.The ImpactHafnia-based ferroelectric materials seem to possess numerous advantages for computer memory. They provide high durability, lower operating power, speed, and the potential to hold data when power is shut down. But scientists do not completely comprehend such materials.This study developed a creative bulk hafnia-based ferroelectric material. The outcomes offer insights into how suc...

source:bismarcktribuneNorth Dakota can’t be accused of not trying when dealing with its resources. Among other efforts, it has focused on renewable energy, has set lofty goals for carbon capture and has been studying a number of clean energy options.The state also is involved in research into whether North Dakota’s lignite coal seams contain rare earth elements that are used to produce touch screens for cellphones, guidance systems for missiles, and motors and batteries for hybrid vehicles.These elements have value in the manufacture of goods and could provide a boost to the state’s economy. I...

source:nanowerk(Nanowerk News) Erbium-doped fiber amplifiers (EDFAs) are devices that can provide gain to the optical signal power in optical fibers, often used in long-distance communication fiber optic cables and fiber-based lasers. Invented in the 1980s, EDFAs are arguably one of the most important inventions, and have profoundly impacted our information society enabling signals to be routed across the Atlantic and replacing electrical repeaters.What is interesting about erbium ions in optical communications is that they can amplify light in the 1.55 mm wavelength region, which is where sil...

source:eurekalertmechanoluminescent materials are subjected to external mechanical stress, they emit visible or invisible light. Such excitation can occur due to bending or gentle pressure, for example, but also completely contact-free through ultrasound. In this way, the effect can be triggered remotely and light can be brought to places that normally tend to be in the dark, for example in the human body. If the ultrasound treatment is to be used at the same time to generate local heat, it is important in such a sensitive environment to observe closely the temperatures that occur. Material sc...
